JEGS Threaded Locking Valve Cover Breather

This threaded locking system is the professional way to solidly mount your breather to your valve cover without welding. It prevents the breather from popping off the valve cover under high RPM crankcase pressures. Works great with the standard 1-1/4" breather hole found on most valve covers. The 2-piece housing design allows easy servicing (i.e. adding oil) and includes a 3/4" hose barb fitting (with a 3/4"-16 threaded size) or a -8AN male fitting for crankcase evacuation systems. Machined from 6061 billet aluminum and clear anodized for superior durability and corrosion resistance with a laser etched JEGS logo.Sold individually. Made in the USA.
